GAS-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 338,422, dated March23, 1886.

Application filed January 27, 1886. Serial No. 189,910. (No model.)

To aZZ whom it may concern:

Be it known that I, ELI O. MoOLoY, a citizen of the United States,residing at Mount Vernon, in the county of Knox and State of Ohio, haveinvented certain new and usefullmprovements in Gas-Regulators, of whichthe following is a 7 full, clear, and exact description, reference beinghad to the accompanying drawing forming part of this specification,wherein the figure represents a sectional view of a gasregulatorembodying my improvements.

The invention relates to that class of devices or apparatus which aredesigned to regulate the pressure and flow of illuminating gas throughthe supply-pipes of buildings; and my invention consists in certainnovel constructions and combination of elements, more particularlydescribed and claimed hereinafter, by means of which I obtain a morecertain and positive action of the valve, with consequent regularity anduniformity of operation, and produce a compact apparatus simple in itsconstruction, and embracing among its advantages durability andcheapness.

To enable others skilled in the art to which my invention appertains tomake and use it, I will now describe its construction and the manner inwhich I have carried it out.

In the said drawing, A represents a suitable gas-holder, which isdesigned to be placed intermediate the gas-meter and supply-pipes of thebuilding, it being provided with couplings a and b, the formercommunicating with the meter and the latter with the supply-pipe,whereby the pressure and fiow of gas through the holder may be regulatedand a uniform pressure of gas throughout the structure maintainedregardless of the pressure from the gasworks.

The holder A is provided withadiaphragm, B, near its center, and fromwhich extends upwardly to the top ofsaid holder a tube or equivalentdevice,C,thereby forming between said tube and the holder an annularspace, D, containing oil or other substance.

Between the diaphragm B and the bottom of the holder Ais secured asecond diaphragm, D, provided with an opening, 0, for the passage of thegas. Around this opening, and extending upwardly from the diaphragm D,is a short tube, d, constructed, preferably, of brass,

and having its upper edge beveled, thereby forming a knifeedged seat fora suitable valve, whose construction and operation I will now describe.

A post, F, projecting upwardly from the diaphragm D, has mounted in itstop a lever, G, the short arm of which has attached to it a valve-stem,e, having a leather disk or valve secured to itslower end, which closesthe opening 0 in the top of the tube d, and automatically regulates thefiow of gas through the holder, as I shall now describe. In the annularspace D in the top of the holder A is placed adome, L, having on itsunder side an eye, 9, to which is attached the upper end ofa verticalrod, M, whose lower end is connected to the long arm of thelever G. Itwill thus be manifest, the valve being open, the gas entering thechamber A finds an eXit through the opening 0 and passes upward throughthe tube 0 and against the top of the dome. Under the pressure of thegas the dome now ascends, and in doing so draws upon the connecting-rodM, which, operating the long arm of the lever G, forces the valvedownward upon its knife-edge seat upon the tube d, and cuts off the flowof gas through the holder. As the gas now contained in said holderisbeing consumed the pressure upon the dome decreases and permits saiddome to sinkin the oil contained in the annular space D, which action,by reason of the elements previously described, opens or raises thevalve and permits the gas to again flow through the holder, the amountof gas passing through the opening being controlled by the distance thevalve remains above the valve-seat. In addition to these devices, theholder has secured to its upper end a suitable frame or bracket, 1?, inwhich is mounted suitable pulleys, R and S, and the dome L has an eye,9, to which is attached one end of a cord or chain, 'I, whose oppositeend is provided with a weight, U, which counterbalances the weight ofthe dome and permits said dome to ascend and descend in the usualmanner.

From this description it is manifest the device, when constructed asherein set forth, is positive in its operation, simple and cheap in itsconstruction, and durable in its character. At the same time, by reasonof the arrangement herein specified,-I am enabled to over-v come many ofthe objectionable features incident to the construction of some of thedevicesused for a like purpose at the present time.

It is well known many gasavorks generate a coal-gas containing tar, aswell as sulphur and ammonia, the former of which has atendency to gum orclog the free movements of the valve and connections, and therefore toimpede the successful operation of the device. In the present case,byresting the valve upon a knife-edge seat, I am enabled to form a tightjoint between the valve and seat, and also pre sent a minimum surface tobe affected by-the action of tar or other foreign substance; also, bypassing the connecting-rod through the tube 0 all danger of the said rodsticking Wis obviated, while in the use of aleather valve the injuriouscorrosive effect of the sulphur and ammonia is avoided.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a gas-regulator, the holder A, provided with inlet and outletapertures, a dia phragm, D, having a tube, (1, projecting therefrom, adiaphragm, B, having an upwardlyextending tube, 0, and a valve supportedabove the tube d, in combination with a dome, a connecting-rod passingthrough the tube 0 a pivoted lever to which the valve-stem is connected,a dome, and a connecting-rod between the dome and lever, substantiallyas herein described.

3. An improved gas-regulator comprising a holder having a diaphragm, D,with opening 0 formed therein, atube surrounding the opening and forminga valve-seat, a post, F, projecting from the diaphragm, a leverfulcrumed in the top of the post, a valve-stem secured to the lever, avalve supported above the valveseat, a second diaphragm, B, having an upwardly-extending tube, G, a dome, a rod within the tube and connectingthe dome and 1e ver, a frame, I, pulleys R and S, the cord or chain T,attached to the dome, and a weight attached to the cord, substantiallyas herein described.
